Abstract: A conveyor assembly which can be mounted on a band saw table to convey lumber to be cut to and away from the saw blade includes two guide/drive subassemblies which are independently positionable on the band saw table on opposite sides of the saw blade, each guide/drive subassembly including two spaced apart gripping roller for contacting an adjacent side of the lumber. The two gripping rollers of one of the guide/drive subassemblies are spring biased towards the gripping rollers of the other guide/drive subassembly to accommodate lumber of differing widths. The two guide/drive subassemblies include respective drive systems to positively rotate the gripping rollers thereof in the same direction and at the same speed, and a transmission chain extends between the two guide/drive subassemblies to connect the two drive systems in such a way that the gripping rollers of one guide/drive subassembly rotate in the opposite direction to the gripping rollers of the other guide/drive subassembly.
